Food for discussion:
In a German aviation forum there is a discussion ongoing rgarding the impact location and flight path.
The conclusion at the monent is that the approximate crash site is at
6,7°S (6° 42' 50'') and 106,73E (106° 43' 30''). Flight direction 210 ° up a canyon.

If linking to a German aviation forum is not OK, I'll remove the link.
